Important Policies to be followed 1. Student Academic Integrity Policy*: MEC upholds the spirit of academic integrity in all forms of academic work and any form of violation of academic integrity shall invite severe penalty. Any benefit obtained by indulging in the act of violation of academic integrity shall be cancelled. All cases of violation of academic integrity on the part of the student shall fall under any of the below mentioned categories: 1. Plagiarism 2. Malpractice 3. Ghost Writing 4. Collusion 5. Other cases If the student fails a module and has a proven case of academic integrity violation in this module, the student is required to re-register the module. This is applicable to first and second offenders of plagiarism. 1. Plagiarism A. First offence of plagiarism I. MEC_AMO_TEM_034_01 If a student is caught first time in an act of plagiarism during his/her course of study in any assignment other than project work, the student will be allowed to re-submit the assignment once, within a maximum period of one week. However, a penalty of deduction of 25% of the marks obtained for the resubmitted work will be imposed. Page 5 of 10 Structural Mechanics 2 (CIVL 0013)-Spring-20-LAB Assignment1-A&B-QP II. Period of re-submission: The student will have to re-submit the work one week from the date he or she is advised to re-submit. III. If the re-submitted work is also found to be plagiarized, then that assessment will be awarded a zero mark. Re-submission of the work beyond the maximum period of one week will not be accepted and the assessment will be awarded a zero mark. B. Second offence of plagiarism If any student is caught second time in an act of plagiarism during his/her course of study (in a subsequent semester), the student will directly be awarded zero for the work in which plagiarism is detected. In such cases, the student will not be allowed to resubmit the work. A warning of suspension shall be issued, and student has to sign an undertaking and undergo counselling session in such cases. 2. Malpractice/Ghostwriting/Collusion A. First offence of Malpractice/Ghostwriting/Collusion If a student is caught in an act of Malpractice/Ghostwriting/Collusion for an assessment component irrespective of coursework or end semester, the student shall fail the module and shall be required to re-register the module B. Second Offence of Malpractice/Ghostwriting/Collusion If a student is caught a second time in an act of Malpractice/Ghostwriting/Collusion for an assessment component irrespective of coursework or end semester, the student shall fail the module. A warning of suspension shall be issued, and student has to sign an undertaking and undergo counselling session in such cases. 3. Third Offence of Academic Integrity Violation If a student is caught a third time in an act of Academic Integrity Violation for an assessment component irrespective of coursework or end semester (in a subsequent semester), the student shall fail the module and also shall be suspended for one semester from the College, as recommended by institutional level academic committee, Chaired by the Associate Dean, Academic Affairs. 4. Fourth Offence of Academic Integrity Violation: If a student is caught a fourth time in an act of Academic Integrity Violation for an assessment component irrespective of coursework or end semester (in a subsequent semester), the student shall fail the module and also shall be expelled from the College, as recommended by institutional level academic committee, Chaired by the Associate Dean, Academic Affairs. 5. Other cases If a student commits an act of academic integrity violation as per the definition of “other cases” mentioned in the previous section or of a different nature, student’s case shall be forwarded to an institutional level academic committee, Chaired by the Associate Dean, Academic Affairs. The MEC_AMO_TEM_034_01 Page 6 of 10 Structural Mechanics 2 (CIVL 0013)-Spring-20-LAB Assignment1-A&B-QP committee shall investigate the case by means of a viva and/or a disciplinary hearing and shall take appropriate decision. The penalty that can be granted to a proven case of academic integrity violation which falls in this category of “other cases” can be a warning/component zero/ module fail/suspension/expulsion depending on the nature and gravity of the offence. 6. Types/Variations of Cases: I. II. III. IV. If plagiarism is detected in any component of one assessment, the deduction in marks will be applicable for the whole assessment, even if only the component or part submission alone needs to be resubmitted. If plagiarism is detected in a group assessment, all students of the group will be considered as having committed an act of plagiarism and the policy will then be applied to all students If plagiarism is detected in any component of a group assessment, the deduction in marks will be applicable for the whole assessment even if only the component or part submission alone needs to be resubmitted. All students of the group would be considered as having committed an act of plagiarism and the policy will then be applied to all the students of the group. If the assessment consists of components or part submissions that could be a group assessment component (e.g. group assignment) and an individual assessment component (e.g. individual reflection), the following will be applicable: a. If plagiarism is detected in the group assessment component, all students of the group will be considered as having committed an act of plagiarism, The policy will then be applied to all students of the group. Group assessment component will be resubmitted as per the policy. b. If plagiarism is detected in the individual assessment component, the individual assessment component will be resubmitted and the policy will then be applied to that student alone. c. For both (a) and/or (b), the deduction in marks will be applicable for the whole assessment. * for further details Refer to MEC Student Academic Integrity Policy in Student Handbook. 2. Late Submission Regulations: It is the students’ responsibility to check all relevant timelines related to assessments. As per the Assessment Policy at MEC, late submissions are allowed for one week (5 working days) for all UG modules with a penalty. In such cases, a deduction of 5% of the marks obtained for the submitted work shall be imposed for each working day following the last date of submission till the date of actual submission. Assessment documents submitted beyond a period of one week (5 working days) after the last date of submission will not be accepted and will be awarded a zero for that assessment. In cases where the submission has been delayed due to extenuating circumstances, the student may be permitted to submit the work without imposing the late submission policy stated above. The extended period of submission will be one week from the original last date of submission. In such cases, the student is expected to submit the supporting MEC_AMO_TEM_034_01 Page 7 of 10 Structural Mechanics 2 (CIVL 0013)-Spring-20-LAB Assignment1-A&B-QP certificates on or before the original last date of submission of the assessment and the decision of extension rests with faculty responsible for the assessment .The late submission policy shall be applied if the student fails to submit the work within one week of the original last date of submission. Students may contact their teachers for clarification on specific details of the submission time if required. 3. Research Ethics and Biosafety Policy To protect and respect the rights, dignity, health, safety, and privacy of research subjects involved including the welfare of animals and the integrity of environment, all student projects are expected to be undertaken as per the MEC Research Ethics and Biosafety Policy. Accordingly the following shall apply.  Research and other enterprise activities shall be conducted by maintaining the high ethical standards consistent with national and international standards and conventions.  Any research at MEC that is categorized as high-risk research shall be subject to review and approval by the Research Ethics and Biosafety Committee.  Research activities involving collection of human or animal tissues and manipulation of microbial, animal or plant cells shall be subject to review and approval by the Research Ethics and Biosafety Committee.  Participants involved in research must be informed about the purpose of research and intended uses of research findings.

INTRODUCTION
The purpose of this assignment is to analyze statically determinate and indeterminate structures
comparing theoretical result with the experimental results. The analysis was divided into three
tasks:
The first one consists in analyze the deflection of simple supported beams changing the variables
like loads, length of span, material, and section dimensions. The aim of this task is understanding
which variable increases or reduces the deflection of a simple support beam.
The second task consists in compare theoretical formulas and robot software to find the reactions
at supports and deflection at midspan changing the loads position in a fixed-fixed beam and a
fixed-propped beam. The aim of this task is understanding how the deflection can increases when
it is changed the load position in a indeterminate beam.
Finally, the last task consists in analyze the reactions and support reactions of frame by using the
software Robot Structural Analysis. Will be observed how the deformation in a frame for different
elements and different loads is.

ANALYSIS OF RESULTS
To generate experimental values for Task 1 it was used ROBOT. It can be observed that all the results
calculated applying the theoretical equations and using ROBOT were the same. This means that the
models made experimentally with the software were made correctly.
From graphs, it is observed that in cases a & b increases in deflection when the load or span are
incrementing. Instead, when the inertia or young modulus in cases c & d are incrementing, deflection
decreases.

Task 2 was performed by using ROBOT to generate the experimental values for the two cases (a & b).
Comparing results of experimental and theory values it was observed that M at left support and R at
right support where the same. In the other hand, the deflection at midspan values for both models (fixedfixed beam and fixed-propped beam) up to 3 significant figures were equal. This is because only 3
decimal places in inertia were used to calculate the theoretical values.

Also, comparing case a with case b we can see that the second one had higher deflection values which
means that the fixed-propped beam has lesser boundary conditions at right support making the beam
more deformable and flexible.

A frame model was performed for Task 3. The element with the highest flexural solicitation was the
upper beam with load W3 and the moment was equal to 201.83 KN-m. Also, the maximum shear force
was in the upper beam with load W3, and the shear force is 69.45 KN. However, the maximum
deflection is not located in the upper beam but is in the righter column. This is due to several variables
that affect the deflection of that element, such as the inertia of the section, the length of the column as
well as the type of support (pinner).
In addition, the support with the maximum reactions was the support B having a Rx=13.75KN,
Rz=126.84KN, and a My=74.03KN-m. If we invert the section assigned for the columns and beams, we
will get a higher moment and shear force in the upper beam but a lower maximum deflection in the
righter column.

CONCLUSIONS
It can be concluded that for the design of a beam it is necessary to have the adequate knowledge of
which are the variables that improve or worsen the deformation in an element. From task one it was
determined that as the span length or acting load increases, the deflection will increase as well.
Therefore, if these variables are fixed for a design then it will be necessary to increase the size of the
section or change the type of material in order to compensate for the increase in deflection.

From task 2, it can be concluded that the position of load and the type of supports can change the
maximum deflection value. Having a support that resists moment we will obtain a lower moment for a
load in the middle of the span than if it did not have it. However, this means a higher solicitation at the
support.

A frame structure is where columns and beams are connected and working together and act as support
for the ...
